DRAM configurations

You can increase your computer’s DRAM up to 384 megabtytes (MB) by adding Dual Inline

Memory Modules (DIMMs) to the three DRAM DIMM slots on the main logic board. See the

Technical Information booklet that came with your computer for information about the type

of DIMMs you must use.

Important This computer uses Synchronous Dynamic Random-Access Memory (SDRAM)

DIMMs. DIMMs from older Macintosh computers are not compatible with your computer

and should not be used even though they fit into the DRAM DIMM slots.

DIMMs can be installed one at a time in any order in any of the memory slots.

To increase DRAM to the maximum of 384 MB, fill all three slots with 128 MB DIMMs.

Video memory configurations

Your computer comes with 2 MB of video memory built into the logic board and a video

memory expansion slot that allows you to expand video memory up to 6 MB. The expansion

slot accepts a 2 MB or 4 MB Synchronous Graphic RAM (SGRAM) SO-DIMM. See the

Technical Information booklet that came with your computer for information about the type

of DIMM you must use. (Your computer may already have an SO-DIMM installed.)

Important Use only SGRAM SO-DIMMS.

About internal storage options

Your computer has one standard SCSI chain, which is capable of transferring data at up to 5

MB per second. The SCSI chain can support up to seven internal and external SCSI devices.

(For information on connecting external SCSI devices, see Chapter 2, “Using Your Macintosh

and Connecting Additional Equipment.”)

There are two expansion bays inside your computer for connecting internal SCSI devices.

The illustration below shows the locations of the expansion bays.

Warning

If your computer came with an internal modem, an Apple-certified

technician or authorized service provider must install video memory because the

modem must be temporarily removed to allow access to the video memory expansion

slot. Only an Apple-certified technician or authorized service provider can remove the

modem. To avoid damaging your computer, do not attempt to install video memory if

your computer came with an internal modem.
